Adaptive function of duodichogamy: Why do chestnut trees have two pollen emission phases?
American Journal of Botany, Volume 110, Issue 8, August 2023., 2023 Abstract Premise Intersexual mating facilitation in flowering plants has been largely underexplored. Duodichogamy is a rare flowering system in which individual plants flower in the sequence male‐female‐male. We studied the adaptive advantages of this flowering system using chestnuts (Castanea spp., Fagaceae) as models.

Reproductive biology of the andromonoecious Cucumis melo subsp. agrestis (Cucurbitaceae) [PDF]
Annals of Botany, 2009 Cucumis melo subsp. agrestis (Cucurbitaceae) is cultivated in many African regions for its edible kernels used as a soup thickener. The plant, an annual, andromonoecious, trailing-vine species, is of high social, cultural and economic value for local communities.

Differential reward in “male” versus “female” pollen of functionally dioecious Solanum
American Journal of Botany, Volume 108, Issue 11, Page 2282-2293, November 2021., 2021 Abstract Premise Five to six percent of angiosperm species exhibit a dioecious sexual system, with unisexual “male” or “female” flowers borne on separate plants. The consequent need for inter‐individual pollen exchange is a special challenge for taxa where pollen is the sole pollinator reward.

Tree of Sex: A database of sexual systems [PDF]
, 2014 The vast majority of eukaryotic organisms reproduce sexually, yet the nature of the sexual system and the mechanism of sex determination often vary remarkably, even among closely related species. Some species of animals and plants change sex across their

TAXON, Volume 70, Issue 1, Page 48-71, February 2021., 2021 Abstract Targeted capture of nuclear genes increasingly contributes to unravelling phylogenetic relationships that hitherto remained unresolved because of limitations of traditional Sanger sequencing. In particular, the study of tropical plant families has been compromised because they often rely on highly degraded DNA obtained from herbarium specimens.

Andromonoecy in Solanum marginatum
Botanical Gazette, 1981 Solanum marginatum is andromonoecious, with long-styled hermaphrodite flowers and medium- or shortstyled female sterile flowers which produce fertile pollen. The morphology of the three floral types is compared. The female sterile type is determined prior to the stage at which the flower buds are visible.

Dicliny in Bouteloua (Poaceae: Chloridoideae): Implications for the Evolution of Dioecy [PDF]
, 2007 The New World grass genus Bouteloua (Chloridoideae: Cynodonteae) comprises 57 species, 13 of which produce unisexual spikelets and hence are diclinous. Andromonoecy, gynodioecy, monoecy, trimonoecy, and dioecy all occur in the genus, and ten species are ...

Reproductive assurance through autogamous self-pollination across diverse sexual and breeding systems [PDF]
, 2015 Pollination becomes a constraint when conspecific plants and/or their pollinators become scarce. Many plant species have evolved autogamous self-pollination as a means of reproductive assurance (RA) under pollination-uncertain environments. So far RA has
